The same part is designated by thesame reference numeral wherever itoccurs throughout the several views.

In its essential features a metallic door embodying my inventionconsists of two sheet metal panels suitably pressed to the requiredshape and contour and secured together at their edges to constitutethedoor, the panels being separated from each other a distance to afford aninterior chamber or reeess' The lock mechanism consists essentially of alocking bolt, an operating lever handle therefor, and a spring normallyacting to maintain the bolt projected. These parts readily separablewith relation to each 7 other and they are not connected through anyscrews or other attaching devices, and the locking bolt is carried in a.housing which is arranged within the ohamber between the door panels andsuitably secured to the outer face of the inner door panel.

Referring particularly to the structure shown 6 designates the outerpanel and Tthe inner panel of the door structure. Each of these panelsis stamped out of sheet metal, the side. and bottom edges of the innerpanel being bent out of the plane of said pane] indicated. at 8, 9,Figs. 2 and 3, and into suitable curved shape or form along the frontedge of the door to receive and overlie the rubber or other bumperblocks and guiding lugs as indicated at 10. At its extreme edge boundingthe verticalsides and lower edge of the door the flanged portions 8, 9,of the inner panel are formed into lips 11, over which are engaged bentflanges 12, at the bounding edges of the outer panel 6, as clearly shownin l igs. 2 and. Of course the inner and outer Wall panels are formedinto the desired shape and contour to follow the outlines of the vehicleor other structure to which the door is to be applied.

The inner panel 7 is pressed into shape to form a depression 13,centrally in the in ner surface thereof, that is, 'the surface whichpresented to the interior of the vehicle body. Across the lower portionof the open face of the depression mseat is secitlred a plate 35,thereby forming the pocket, with which (automobile doorsare 0rdinaryprovided. If desired a strengthening bumper or filler plate 36 may beinserted between the outer surface of the wall of the depression and theinner surface of the outer door anel 6, as clearly shown in Figs. 1 and2, a though this is not essential. This structure of'door and pocket isexceedingly simple, efiicient, satisfactory and inexpensive to produce.The door hinge straps 14 through which the door is hinged to theadjacent post of the doorwayaresuitably secured into the door structureat the rear edge thereof. A simple and very satisfactoryway ofaccomplishing this is shown whereinthe-ends37 of the hinge straps extendthrough slots in the. inner panel 7, into the space or chamber betweenthe panels, and are welded or otherwise integrally connected to theinner surface of the flange 8 at therear vertical edge of the door. Thisproduces a strong durable structure which is economical to manufacture.Adjacent the front edge of the door structure the inner panel isprovided in its inner surface with a depressed seat portion 15 stampedtherein to receive and accommodate the handle 16 of thelock mechanism.The inner panel is slit at 17 to permit the lever 16 to extend throughthe slit' and into the. interior chamber 18, formed between the twopanels 6, 7. The bolt 19 is housed within chamber 18, and its outer endprojects through an opening formed in the flange 9 at the front edge ofthe inner panel, said bolt being retained in place by a housing or strap20, in the I form of a metal channel 20, havin edge flanges which areapplied and securedtothe inner surface of the panel 7 or to a plate 38which isapplied to the inner surface of said panel. This plate has alooped end 39 which carries a stud 21 which is straddled ,by a forkformed at the inner endof lever 16, when said lever is in workingposition, thereby forming a fulcrum about 'which said lever rocks inoperating the bolt. The bolt is engaged in any suitable manner by thelever 16. A simple arrangement is shown wherein the bolt on its innerfaceor Surface is recessed as indicated at "22, and

in assembling the bolt and its operating lever 16, the latter passestransversely through said depression. On its rear edge the lever 16isformed, with a rounded proi j'ecti'on 23 which works against theinclined wall or surface 24 which forms a rear boundary of the depressedseat 22 in the bolt. Thismaterially reduces friction and secures an easyoperation of the bolt. Adjacent the extremity of the rounded projectionv23 of the' leversa'id lever is provided with shoulder 25, see Fig.4,into which extends the extreme outer corner-26 of the adjacent 'wallofthe recess-22, thus f'ormingastopto normally retain the lever in itsassembled relation with respect to the bolt." A-coil spring 27 isinserted within the housing 20 and normally exerts its tension againstthe inner end of the bolt in a direction tending to project the boltoutwardly. The engage ment of the lever 16 in the depression 22 of thebolt, of course prevents the bolt fromthe bolt. While this is a simplearranger Y ment my invention is not to be limited or restricted in thisrespect.

In order to assemble the parts of the lock the spring27 is inserted intothe housing 20 and then'the bolt is inserted so as to bear against thespring and is pressed inwardly as far as possible. This will bring theseat 22 in the bolt in-line with the slit or opening 17 in the innerpanel and into position for the lever 16 to be inserted through saidslit 17 and through the housing 20 and through the seat or depression22, and into position for the forked end thereof to engage the stud 21,the corner 26, when the bolt is released after inserting the lever,snapping against the shoulder 25 and the rounded surface or projection23 bearing against the wall 24 of the recess 22." The parts are now inpositionassembled for operation. Inorder to remove the lock mechanismthe reverse of the above operation takes place that is to say, the boltis pressed inwardly as far as it will go, this action releasing theprojection 26 from shoulder 25, and then the lever 16 may be readily andeasily withdrawn endwise through the seat 22. The. bolt may then bepulled out and the spring removed from the housing. A look mechanismsuch 1 subj'ected to the usual enameling heat with the spring of thelock mechanismremoved and consequently the danger of injuringthe temperof the spring through the action .of the enameling'heat is" avoided.

It will also be. observed'that no tool is re quired in order to effectthe assembling or removal of the lock structure. .If desired, and inorder to impose a desirable friction upon the bolt operating lever,

lot!

a nd'tohold the same in the proper plane of operation a rib may bestamped in the de piesaedi portion of the inner panel and arr, ra; gedtoextend transversely of the lever 16 5 and-against which the leveroperates.

Interposed between the upper edges of the inner and outer anels (i, 7, Iprefer to insert ablemeans f terialor strip for the door. A simple arrangement is shown wherein a box sl'laped stamping 29 is inserted betweenthe upper edges of the stampings 6, 7, said stampings I at their-upperedges being suitably bent out l' f wardly or away from each other toform asnitable seat for the member 28 therebetween. and the extreme edgeof one of said panels, fasdfor instance, the outer panel 6 bent UMBI'the u per side or-edgelof the member All 0 the parts constituting thedoor, ttore, and; including the housing may int rally eeenreditogetheror to their ad arts integrally in any suitable or nt manner.
